Interface Board Design
Our team has extensive experience in designing probecards for various applications and offering services to many leading probecard vendors around the world. We get repeat business requests due to our capability to deliver quality designs on schedule irrespective of complexity.
Probecard designs of high pin count and densities are more than routing intensive work and routing of signal and ground traces takes morethan 50 percent of total design time. Also the traces needs to be equally spaced all over the spider area to achieve board planarity and the lengths should be matched to zero tolerance for greater performance. It needs more manpower to complete design in short duration. CIS interconnects Private Limited has the skill to overcome challenges involved in designing a probecard in a short duration by extending the capability of the EDA tools through its customization capability. Our in-house software team developed intelligent software tools and utilities to help the designers to achieve fast turn around in each design process. The whole design process is tool driven and we constantly innovate new tools to help manual routing. Our in-house software team developed numerous software tools to help the designers to achieve fast turn around. Our team can route 2000 traces in a day, thus we are able to meet timelines specified by the customer.
